The interesting thing about the current administration is that they are keen to reduce the possibility of workers having effect on services, but don't necessarily practice what they preach. A good example is my union recently had a vote for industrial action over pay. And although the result was largely in favour of action, because the turnout was less than 50% of the membership under the new laws regulating union activity, it requires a basic majority to turnout otherwise action is illegal. Meanwhile in various other public votes, elections etc this is not a requirement. So its kind of Democracy Minus, the lower down the food chain you are, the more the government legislates against you.
Meanwhile in Parliament, it is perfectly acceptable for Members to boycott, not turn up for important legislation debates & votes, even talk them out of Parliament by simply forcing the debate beyond the allocated timescales (Philip Davies, MP for Shipley I'm looking at you). So those people who think its a good thing to legislate against union action beware. Once the unions are all but toothless (and many already are), they will start to erode into your say too (for what it is these days). Its a slippery slope none of us really want!
